concern:

I, ULYssEs H. HILL, a citizen of the United States, residing at 405 Sentafee street, El Paso, the county of El Paso and St ate of Texas, haveinvented a new and useful Auto-Door Stop, of which the following is aspecification.

This invention relates to door-stops.

The objects of the invention are, the provision in a merchantable form,of a device of the above mentioned class, which shall be inexpensive tomanufacture, facile in operation, and devoid of complicated parts; adevice which shall hold a door positively and firmly; a device which maybereadily attached to and removed from a door; a device which shall notimpede the passage of persons through the door-way; and ally, a deviceand detract nothing from the appearance of the apartment within which itis employed.

With these and other objects in view, as will hereinafter more fullyappear, the invention consists in the novel construction and arrangementof parts hereinafter described, delineated in the accompanying To allwhom it may Be it known that claims, it being understood that variouschanges in the form, proportions, size and minor details of thestructure may be made without departing from the spirit or sacrificingany of the advantages of the invention. Similar numerals of referenceare employed to indicate corresponding parts throughout the severalfigures ofthedrawings.

In the accompanying drawings, Figure 1 shows in perspective, myinvention attached toa door; Fig. 2 is a perspective, showing in detailupon an enlarged scale, the late 1, the catch-pin 7 and the screw 13 witwhich the plate 1 is pivotally attached to the lintel 14 of thedoor-way.

In carrying out my invention, I provide primarily a thin and relativelynarrow plate 1, having a longitudinally disposed slot 2 near one of itsterminals. From the inner edges of the slot 2, near theend of the plate1, project inward, the shoulders 3, so disposed as to cause the slot 2to terminate in a substantially c'rcular opening 4. Near the oppositeend of the plate 1, I provide means for mounting the said platepivotallyupon the under surface of the lintel of a door way, the opening5, adapted to receive an ordinary drawings 2 and particularly pointedout in the appended screw 13, serving the purpose in the embodiment ofthe invention shown. The opening 5 should be countersunk from the underside of the plate 1 as shown in dotted line at 11, and the edges of theslot 2 beveled inward, upon the upper side of the plate 1 as shown at 6.

, In connection with the plate 1 is employed the catch-pin 7. Thecatch-pin 7 forms the connection between the plate 1 and the door I2 andcomprises a shank 8 adapted to enter the upper edge of the door. Theshank 8 may be variously fashioned; I have shown it as threaded, butobviously it may be of any other form adapted to enterand retain a holdupon, the

door 12. The catch-pin 7 is slotted lon itudinally to form the resilientarms 9 and these arms 9 terminate at their upper ends in like,symmetrically disposed heads 10, their under surface adapted to conformto the bevel 6.

In applying my invention, a' common screw 13 is passed u ward throughthe opening 5 and inserted mto the lower surface of the lintel 14 of adoorway, the under side of the screw-head seating well into the counter?sunk edge 11 of the opening 5. The plate 1 is then swung out with theslot 2 across the upper edge of the door 12 and through the slot 2 thecatch-pin 7 is introduced into the door 12, the under side of the heads10, seating in the bevel 6, maintaining a sliding contact with the uppersurface of the plate 1 and holding the plate 1 to the upper edge of thedoor 12. The position of the plate 1 upon the lintel 14 and the point ofattachment to the door 12 may be ascertained by experiment, bearing inmind the angle which it is desired that the door 12 shall take whenretained in an open position; and it isobvious that the angle may bevaried through a wide range by changing the position of the plate 1.

In operation, as the door 12 is swung open, the catch pin 7 will travelin the slot 2 until the shoulders 3 are reached, when the resilient arms9 will be forced together. As the door moveson to the limit of itstravel, the resilient arms 9 will pass the shoulders 3, enter thecircular opening 4, assume their normal position and then retain thedoor in an open position until a force suflicient to overcome theirresiliency causes them again to engage the shoulders 3 and pass into.the slot will turn pivotally upon the lintel 14 and pass out of sightbetween the lintel 14 and the door 12.

Having thus described claims are as follows;

1. In a device of the class described, a thin and relatively narrowplate having a longitudinal slot; shoulders v projecting inward from theedges of the slot; means for mounting the plate pivotally u on thelintel of a door-way; means adapte to enter the upper edge of a door andengage yieldingly the inwardly projecting shoulders.

2. 1n a device of the class described, a thin and relatively narrowplate longitudinally my invention, my

. slotted near one of its terminals and provided with a circular openingnear the other terminal shoulders projecting inward from the edges ofthe slot; slidably mounted in the slot,

a headed screw, lon ing the under side 0 its head in sliding contactwith the upper surface of the plate.

3. In a device of the class described, a thin and relatively narrowplate longitudinally slotted near one of its terminals and provided witha circular opening near the other terminal shoulders proj ectln inwardfrom the edges of the slot, slidab y mounted in the slot, a catch-pinhaving resilient arms-adapted to enga e yieldingly the inwardlyprojectin shoul ers.

n testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
